APPARATUS FOR AUTOMATICALLY CONTROLLING THE uNwmo'me F ROLLS OF PAPER.

SPECIFICATION forming part of Letters Patent No. 773,517, dated October25, 1904,

Application filed February 9, 1904. Serial No. 192,794. (No model-l Toall whom it may concern.-

Be itknown that I, THOMAS MERRIFIELD NORTH, a subject of the King ofGreat Brit- .ain and Ireland, and a resident of Altrincham,

in the county of Chester, England, have invented certain new andusefulApparatus for Automatically Controlling the Unwinding of Rolls ofPaper; and I do hereby declare'the following to be a full, clear,andexact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

When it is desired to produce a newspaper of ten or twelve pages inprinting and folding machines adapted normally to. produce a newspaperof, say, eight pages, the extra number of pages must be printed andrewound into a roll beforehand and afterward unwound from this roll andrun in and associated with the paper on whichthe main printing iseffected.v

This operation has hitherto necessitated the constant and most carefulattention of the operator in order that the cutting of the said sheetsmay be effected at or about the middle of the transverse margins,.itbeing almost impossible to unwind a roll so that the said middle partsof the margins shall always be presented to the knives at the properinstant. In these machines means have generally been provided wherebytheoperator may cause the unwinding of the previously-rewound roll to.be accelerated or retarded, according to whether the web of this roll isin arrear or advance of its proper position relatively to the knives;but as this regulation has been entirely dependent upon the keenness ofsight and dexterity of the attendant the results have been far fromsatisfactory.

named extra pages and to the web, roll, and

printing appropriate thereto, and the word main .is applied to the pagesto which the said extra ones are added and to the web,

roll, and printing appropriate to such main pages.

Fig. 5 is a sectional elevation on the line5 5 of Fig. 8 with a part broken away so as to expose other parts whichwould otherwise be obscured. Figs. 6 and 7 are views generally similarto Fig. 5, but showing the parts in ditferent operative positions. Fig.8 is a horizontal section on the line 8 8 of Fig. 6. Fig. 9 is a sectionon the line 9 9 of Fig. 6. Fig. 10 is a plan of a detached portion ofFigs. 11 and 12 are part-vertical sections taken, respectively, on thelines 11 11 and 12' 12 of Fig. 9. Fig. 13 is a plan of a portion of aninset-web in its correct position. Fig. 1 L is a plan of a portion of aninset-web in arrear of its correct position; and Fig. 15 is aviewsimilar to Figs. 13 and 14:, showing the inset-web in advance of itscorrect position.

the mechanism shown in Figs. 5, 6, 7, and 8.

According to this inventionfor each sheet to be cut from the inset-web 1two holes 2 3 are punched in the margin thereof, preferably the centermargin 4:, as shownin Figs. 2, I3, 14:, and l5,while the said sheet isbeing printed, the holes at every part of the'web bearingexactly thesame relation to the printedmatter 5 adjacent thereto. These holes 2 3,as hereinafter described, serve for automatically ef' fecting thecontrol of the webs travel.

In the accompanying drawings the, printing matter 5 is not representedas such. The sites occupied by it are indicated merelyin outline, theother lines appearing in Fig. 2 being added to indicate the arrangementof the columns. p 7

The unwinding apparatus, which is shown in its entirety in Figs. 1 and 2and with which the above-named controlling means are incor:

porated, is situated, preferably, between the printingpress and thecutting and folding mechanism, none of which form part of the presentinvention and are therefore not represented in the accompanyingdrawings. The main web 6, Fig. 1, and the inset-web 1 are led,respectively, from the said press and unwinding apparatus directly tothe folding and cutting mechanism.

In the unwinding apparatus the inset-roll 7 to be unwound rests upon twocylinders 8 9, Fig. 2, the respective shafts 10 and 11 of which aresupported in the two side frames 12 and 13 of the machine and are gearedtogether through spur-wheels 14 15, fast on the said shafts,respectively, and an intermediate wheel 16, running loosely upon a shortshaft or stud 17, Fig. 1, fast in the frame 12. By these means the twocylinders 8 and 9 are caused to rotate in the same direction, asindicated by the arrows in Fig. 1, and at the same peripheral speed,which latter, however, is automatically varied through the intermediaryof the above-mentioned holes 2 3 in the inset-web 1, as hereinafter morefully explained. The spindle 18, on which the roll 7 is mounted, isjournaled in two shoes 19, free to move vertically on guides on the twoside frames 12 and 13 in the ordinary well-known manner.

At one end the shaft 10 projects outward beyond the frame 12 and is freeto rotate in a bearing-standard 21. On this shaft 10 and between theframe 12 and standard 21 is secured a conical pulley 22, situated withits periphery closely adjacent to that of another conical pulley, 23,fast on a-shaft 24, driven positively by any suitable means. (Notrepresented in the drawings.) The said shaft 24 may, for example, beconveniently driven from either the press or the folder, and it issupported and free to rotate in hearings in the two side frames 12 13and standard 21 or in any other suitable manner. The larger end of eachconical pulley 22 23 is adjacent to the smaller end of the companionpulley, and around the positively-driven (or, as it is herein called,first) pulley 23 is loosely encircled a strap 25, which is nippedbetween and in frictional contact with that pulley (23) and the other orsecond pulley 22. This strap 25 is capable of being adjusted edgewisefor varying the speed of rotation of the second pulley 22 in relation tothat of the first one, 23, and for that purpose it is engaged with astrap-shifter 26, Figs. 1, 2, and 4, connected to the lower end of alever 27, pivoted at 28 to a bracket 29, fast to the adjacent side frame12 and to whose upper end is suitably connected a screw-threaded rod 41,hereinafter more particularly referred to.

The before-mentioned shaft 24, through miter-gearing 30, an upstandingshaft 31, and miter-gearing 32, is in operative connection with theshaft 33 of a horizontal registeringcylinder 34. The shaft 33 isjournaled in the upper part of the two side frames 12 13 and throughsuitable gearing 35 36 37 rotates (at the same speed and in the samedirection as its own rotation) a horizontal shaft 38, secured to one endof a body or cage 39, whose other end is supported by a coaxial hollowshaft 40, concentrically within which is situated the before-mentionedscrew-threaded rod 41. The two coaxial shafts 38 40 of the cage 39 aresuitably journaled in the two side frames 12 13, their common axis beingparallel with the axis of the registering-cylinder 34. ()f theabovenamed gearing 35, 36, and 37 the spur-wheel 35 is rigidly securedon the shaft 33, the intermediate wheel 36 is free to rotate on a stud42, fast to the side frame 13, and the wheel 37 is fast on the shaft 38of the cage 39.

The registering-cylinder 34 and the cage 39 are timed to make onecomplete rotation (in the directions indicated by the arrows in Figs. 5,6, and 7) for each sheet to be cut from the web 1. The circumference ofthe registeringcylinder 34 is equal to the length of each insetsheetthatis to say, the length represented by the distance between the two dottedlines 43 in each of the Figs. 13, 14, and 15, and, as shown in Fig. 8,in which figure only the central part of the registoring-cylinder 34 isrepresented, that cylinder is formed in two eoaxial parts, both rigidlysecured to the same shaft 33 and at a sufiicient distance from eachother to accommodate between them a stationary cam 44. This cam 44 isprovided with an opening 45, within which the shaft 33 is free to rotatewithout contact, and the said cam is rigidly secured by a bolt 46 orotherwise to a bar 47, rigidly supported by the two side frames 12 13.One of the cylinder parts (in the example represented it is the rearpart) is provided with two diametrically opposite holes 48, each forreceiving the outer end of a pin 49 or 50, capable of slidingtherethrough and through a guide 51, fixed to the end wall or head 52 ofthe said cylinder part, this sliding motion being in the direction ofthe axis of the pin 49 or 50 and radial to the cylinder-shaft 33.

Each of the sliding pins 49 50 is acted on by a spring 53, which alwaystends to move it into its outermost position, in which latter (see thepin 49 in Figs. 6 and 8) its outer end projects beyond the periphery ofthe registering-cylinder 34. When the pins 49 50 are not projectedoutward by the springs 53, their outer ends do not extend beyond theperiphery of the registering-cylinder. The sliding pins 49 50 are alsoacted upon by independent withdrawingmechanisms mounted on the cylinderhead 52 diametrically opposite each other. As each of these mechanismsis similar in construction and operation to the other, the followingdescription of one is equally applicable to both.

. The sliding pin say the pin 49is engaged with the vibrating end of onearm, 54, of a cylinder-head 52, this arm being forked and Y clearly inFig. 10, is formed preferably, in:

pin 49.

engaging between two collars 57, .faston the A second arm, 55, of thelever 54 55 56 is provided with an antifriction-roller 58,

adapted to travel upon the periphery of the above-named stationary cam44, while the third arm, 56, has pivoted to it a pawl 59, which is actedupon by'a spring 60, secured to the said arm 56 and is adapted to engagea crank-pin 61, projecting from a tumblerdisk 62. This tumbler-disk, asshown most tegrally with a grooved locking-ring 63 and an edge cam64 andis capable of rotating upon a stud 65, fixed'in the cylinder-head 52,andit is provided with three peripheral recesses 66 67 68, situated atninety degrees apart, and amutilated or flattened portion 69 between theperipheral recesses 66 and 68 and adjoining the last-named recess, asshown in Figs. 5, 6, and 7. A spring-detent 7 O, mounted on thecylinder-head 52, engages with the grooves 71 of the locking ring 63 toretain the tumber-disk 62 in any of its definite poe sitions until it ispositively moved from such positions, as next described. On the station?ary cam 44 or the bracket, carrying the same is provided a stud orabutment 72, which projects into the path of the tumbler-disk-62, sothat the peripheral recesses 66 67 68 of the latter may atsuccessiverevolutions of the said disk about the axis of the shaft 33 succause thetumbler-disk 62 and the locking:

. ring 63 and cam 64, connected thereto, for each such engagement to beturned aboutthe axis of the stud through an angle of .ninety de grees.The cam 64 is adapted to operate on one arm, 7 3, of a spring-controlledbell-crank lever 73 74, pivoted on the cylinder-head 52, and whose otherarm, 74, is adapted to act on the before-mentioned pawl-carrying arm 56,as shown in Figs. 6, 7, and 8, so as to retain the sliding pin 49 in'itswithdrawn position during the time that the three-armed lever 54 55 56is out of operative contact with.

the stationary cam 44-.

The before-mentioned rotating body or cage 39 carries two short shafts75 7 6, parallel with and on diametrically opposite sides of the commonaxis of the before-mentioned shafts 38 40, and 'a third short shaft 77,the shafts 75 76 being rotatably and the shaft 77 non-rotatablysupported in the two ends of the said cage. These two cage ends areconnected by three rigid bars 7 8,parallel with the axis about which thecage rotates and constituting integral parts of the cage. On each of thetwo diametricallyopposed shafts 75 76 is secured a star-wheel 79 80,respectively, the free ends of whose arms are adapted to project intothe path of the before-described sliding pins 49 50 of theregistering-cylinder 34, and there is also secured thereon a spur-wheel81 82, respectively,

gearing with a pinion 83 84, respectively, adapted to rotate .freelyupon. one end of a nut 85, fitting on the before-described screwed rod41, as shown most clearly in Figs. 8 and 9. The spur-wheel 81 on theshaft 75 is in 7 direct engagement with its pinion 83; but, the otherspur-wheel, 82, engages its pinion 84 through an intermediate wheel 86,mounted on the shaft 77. By these means the rotation of each star-wheel79 about its axis 75 will cause the nut 85 to rotate in adireetion thereverse of that due to the rotation of the other of such star-wheelsabout its axis. The shaft 75 is prevented from moving longitudiabuttingagainst opposite ends of the cage, 7 and, similarly, .by the wheels 80and 82 abut: I

ting against the two ends of the cage 39 the shaft 76 is prevented. frommoving endwise 8 5 therein. The shaft 77 is secured in the rotating bodyor cage 39 by a screw 88, (shown in dotted lines in Fig.9) whichprevents its rotation, and the wheel 86 is free to-rotate on I the saidshaft and is prevented frommoving 9 sidewise thereon by being juxtaposedbe:

= tween one end of the cage and acollar 89, rigidly secured on the shaftin any suitable .manner.

The bosses of the two starwheels'7 9 80. are

. provided withperipheral grooves 79, (shown' in dotted lines in Fig.6,) with which engage spring-detents 79 1, (Shown in dotted lines inFig. 6 and one of which is also shown in full lines in Fig.8.) Thesedevices serve for re- I00 taining the star-wheels in any position towhich they may be rotated by contact with the sliding pins 48 49. t V VThe nut 85 is prevented from moving longitudinally in the cage 39. bybearing at one 5 I end against a boss 90, formed on one of the cageends, and at its other endagainst a boss or guide9l, which, as showninFig. 9,-may

be formed integrally with one of the before: mentioned bars 78 andserves to. guide one 1 end of the screwed rod 41. This screwed rod isprevented from rotating independently of Y the cage 39 by a suitablefeather 92, Fig. 8,

fast to the said rod and engaging with a groove 93 in thebefore-mentioned boss 90. 15 The pinions 83 84 are capable of engagingthe nut 85, one througha left-handed clutch and the other through aright-handed clutch.

A convenient arrangement of these clutches is that shown in thedrawings,particularly Figs. 6, 8, 9, 11, and 12, which consists of the nut 85being formed with two sets of ratchetteeth 94 95, one set the reverse ofthe other,

and the pinions 83 84, each having a cylindrical flange96 encircling oneset of the said 5 ratchet-teeth, rollers 97 being interposed between theratchet-teeth and respective surrounding fiange 96. I

. The before-ri1entionedholes2 3, Figs. 2,13,

14, and 15, which are punched in the inset 3 web 1, are at aslightly-different distance apart than the peripheral distance betweenthe holes 48 in the registering-cylinder 34, through which the slidingpins 49 50 operate,

- and the webl is so adjusted that when it is in its proper workingposition the hole 2 is slightly in arrear and the hole 3 is slightly inadvance of the respective sliding pin 49 or 50, as shown in Fig. 13,wherein and in Figs. 14 and 15 the said pins are representeddiagrammatically in different positions relatively to the holes 2 3.

The'apparatus is provided with the necessary rollers 98 and 99, Figs. 1and 2, for guiding the inset-web 1 around the register ing-cylinder 34and another roller, 100, for guiding the said web toward the main web 6,the inset-web 1 and main web 6 passing together from this roller directto the cutting and folding mechanism.

In the operation of the before-described apparatus and so long as theinset-web 1 maintains its proper working position, and consequentlypresents its margins properly to the knife, neither of the holes 2 3 inthe said web will register with its respective sliding pin 50 or 49, asshown in Fig. 13, the said pins being therefore retained in theirretracted position out of reach of the respective star-wheels 79 80,which then move as if in one piece with the cage 39. When, however, theinset-web 1 is at the rear of this position, as indicated in Fig. 14,the hole 3 therein registers with the corresponding sliding pin 49,which by its spring 53 is immediately projected through the said hole,and consequently, through the further rotation of theregistering-cylinder 34, as shown in Fig. 6, caused to turn thestar-wheel 79 about its own axis in the direction indicated by thearrows adjacent to that wheel in Figs. 5, 6, and 7. This rotation of thestar-wheel 79 about its own axis through the spur-wheel 81, pinion 83,and appropriate clutch 94 96 97 rotates the nut 85 in the direction ofthe arrows at in Figs. 5, 6, and 7that is to say, in the same directionas but at a quicker speed than the rotation of the cage itself. By thesemeans the screwed rod 41 is moved toward the front of the machine, andthereby through the lever 27 and strap-shifter 26 moves thefriction-strap rearward that is to say, toward the right of Fig. 2so asto cause it to be nipped between a larger part of the conical pulley 23and a smaller part of the pulley 22, and thereby cause the tworoll-supporting cylinders 8 9 to rotate at an accelerated speed, andconsequently accelerate the unwinding of the roll 7. The unwound portion of the web 1 is thus fed more quickly to the folding and cuttingmechanism, and the hole 3 is thereby moved out of register with the thenwithdrawn registering pin 49, thus causing the normal condition ofworking to be restored.

W hen the inset-web 1 is in advance of its normal position, the hole 2thereof registers with the corresponding sliding pin 56, which by itsspring 53 is immediately projected through the said hole, andconsequently through the further rotation of the registering-cylinder 34caused to turn the star-wheel 80 about its own axis in the directionindicated by the arrows adjacent to that wheel in Figs. 5, 6, and 7.This rotation of the starwheel 80 effects the rotation of the nut 35 ina manner almost identical with that already explained in connection withthe star-wheel 79, the only difference being that the nut 85 is rotatedin the opposite direction, owing to the pinion 84 being geared to thespur-wheel 82 through the intermediate wheel 86 instead of, as in theformer case, the pinion 83 (which corresponds with the pinion 84)gearing directly with the spurwheel 81. By these means the web 1 is fedto the folding and cutting mechanism at a slightly slower speed, thehole 2 being thereby moved out of register with the then withdrawnregistering pin and the normal condition of working being thus restored.The outward movement of the sliding pin 49 or 50 also brings the arm ofthe appropriate three-armed lever 54 55 56 into operative contact withthe stationary cam 44 and the pawl 59 into engagement with the crank-pin61, so that by the rotation of the registering-cylinder 34 the slidingpin 49 or 50 is withdrawn into its normal position and the stationarycam 44, lever-arms 55 56, and pawl 59 cause the a1 )propriatetumbler-disk 62 and the rotating cam 64, integral with that disk, toturn through their first ninety degrees, and thereby, as shown at thelower part of Fig. 7, bring the recess 66 of the tumbler-disk intoposition to engage the fixed stud or abutment 72. During this lirstninety degrees of rotation the cam 64 by acting on the appropriatebell-crank lever 73 74 causes the arm 74 of such lever to move from aposition such as that in which it is shown in Figs. 5 and 6 to aposition such as that in which it is represented at the lower part ofFig. 7, in which position the said arm bears upon the leverarm 56, andthereby through the arm 54 of the. corresponding lever holds theappropriate pin 49 or 50 in its withdrawn position. \Vhen the furtherrotation of the registering-cylinder 34 brings this recess 66 up to thesaid lixed stud 72, the tu mbler-disk 62 and rotating cam 64 are turnedthrough their second ninety degrees, the lastnamed bell-crank lever '73'74 still remaining in contact with the three-armed lever 54, 55, and56, and thereby retaining the sliding pin 49 or 50 in its withdrawnposition. At the next rotation of the registering-cylinder 34 the recess67 of the tumbler-disk 62 engages the fixed stud 72 and the said disk isturned through its third ninety degrees, the sliding pin still beingretained in its witlnlrawn degrees of rotation.

position, as during the last preceding ninety At the next ensuingrotation 'of the registering-cylinder 34 the recess 68 of thetumbler-disk 62 engages the fixed stud 72- and the said disk and theattached cam 64 are turned through their fourth ninety degrees, thuscompleting their rotation, at which stage the appropriate bell-cranklever 7 3 74'has released the three-armed lever 54 55 56 and sliding pin49 or 50 and the mulilated portion 69 of the tumbler-disk 62 is turnedoutward. so that the latter will not be further operated until thelast-named three- .armed lever 54 55 56 shall next be brought intooperative contact with the stationary cam 44 through the passage of thesliding pin 49 or 50 into its respective hole 3 or 2 in the The objectof positively retaining the ing pin 49 or 50 within theregistering-cylinder 34 during parts of the rotation of the tumbler-disk62 is to give the inset-web 1 sufficient time to adjust itself beforeallowing the said pin to again pass through the said web; but theproportion of such rotation during which the said retention is exercisedmay be varied according to requirements.

The before-described apparatus is capable of being variously modifiedwithout departing from the essential features of the invention. Forexample, although the sliding pins 49 50 are herein described asdisposed on diametrically opposite sides of the axis of theregistering-cylinder 34 and the two starwheels 79 80 are described ascorrespondingly disposed on diametrically opposite sides of the axis ofrotation of the cage 39. these devices may be arranged in any otherdesired manner so long as the correspondence between them is maintainedand so long as the holes in theweb are positioned to suit sucharrangement.
